Let me know if you need anything from me. > Hello, Nick. Awesome work!!! Let me ask a question. Zram compress and decompress a small data (a page) and your github site says that using predefined dictionary would be helpful in this situation. However, it seems that compression crypto API for zstd doesn't use ZSTD_compress_usingDict(). Is there any plan to support it? Thanks.
